Title: Die casting method for forming female screw
Inventor: TAKANEZAWA YOSHITAKA
IPC: B22D17/22
Filed: 1989-01-11
Abstract: PURPOSE:To simplify tapping process by arranging a motor as possible to automatic regular rotation, reverse rotation and stop, a gear for changing the rotation of the motor into reciprocating movement and rotating movement and making a cope pin rotating and sliding along a female screw and returning back from inner part of a die casting product. CONSTITUTION:The cope pin 6 for forming the female screw receives signals of die opening, injecting finish, etc., from the die casting machine body to digital controller 15. Rotation is changed with the gear with a controller 15 and stroke movement is executed while rotating and the pin 6 is entered cavity 3, and after die casting forming, the movement to be evaded from the formed female screw white rotating is executed. The motor 8 controls the regular rotation, reverse rotation, stop and start with a controller 15, and rotation of the motor is changed into stroke and rotating movement to the cope pin 6 having ball screw with the gear 9. The core pin is evaded from the die casting product 17 along the formed female screw to form the die casting product without breaking the formed female screw.

Title: Semiconductor integrated circuit device
Inventor: YAMAGUCHI SHUHEI
IPC: G11C11/416
Filed: 1990-01-10
Abstract: PURPOSE:To accelerate a differential amplifier circuit by enlarging power supply and temperature margins by an MOS transistor, to which current mirror connection is executed, and suitably providing a bipolar transistor. CONSTITUTION:Input signals IN 1 and 2 are received by first and second input circuits 11 and 12 equipped with the MOS transistor, to which the current mirror connection is executed, and sent to a differential amplifier circuit 13 while being inverted. When the signals are received from the circuits 11 and 12 by first and second bipolar transistors 24 and 25, the differential amplifier circuit 13 is immediately operated and immediately sets one signal at H. With this operation, the gate potentials of first and second NMOS transistors 22 and 23 are changed and the transistors are turned ON/OFF so as to set the other output at L. As a result, the level of the output signal is changed to H or L in a binary manner. Thus, by suitably providing the bipolar transistor, the differential amplifier circuit is accelerated.

Filed: 1980-01-18
Abstract: PURPOSE: To reduce an operation cost and a dissolved oxygen treatment cost by contacting a liquid to be treated which is supplied in a reverse osmosis liquid separation apparatus with a pressure reduced gas.  
     CONSTITUTION: A stock liquid to be treated is introduced into a container 1 from a nozzle 6 through a line 4 and the container is evacuated by a vacuum pump 3 or an ejector, an aspirator or the like. The liquid to be treated is scattered from an upper part of the container 1 and degassed until reached to a lower part of the container 1. A purpose of the degassing is to remove dissolved oxygen in the stock liquid to be treated. The supplied stock liquid degassed by contacting with a pressure reduced gas is accumulated in a degassing water sump 2 of the lower part of the container 1 and sucked by a pump 8 to be supplied to the reverse osmosis separation apparatus 9 and, herein, separated into a permeate 10 and a concentrated water by the reverse osmosis separation. By carrying out the above described process, the operation cost is only a cost required in operating the vacuum pump or the ejector of the vacuum container and, further, because an adding amount of a chemical agent after vacuum operation is minute, a total cost can be reduced.
